☀️ Solar panels in Luxembourg: what do I get for the power I feed in?

The short answer

If you produce more than you use, the surplus goes into the grid. How you are paid for it depends on the national scheme.

📜 The rules in Luxembourg

Solar panels

New solar installations can choose a buy-back contract with the grid operator at a regulated price for 15 years (only if no 50% investment grant was used), or sell surplus to a supplier under a market contract. Self-consumed power is free of network charges and taxes.
